Pulgito’s country was attacked, and many of the men who were defending it suddenly disappeared from the face of the earth. Where are they? Who killed them or took them away? And Why? Pulgito is the only one with the courage and determination to venture outside their country and find out what happened. But his mission is an extremely difficult one, for the attackers are The Gorgos, half-snake-half-crocodile monsters of gigantic size that live at the centre of the Earth: a dark, subterranean country called Gravilandia. An original, funny and moving fantasy novel that will keep you hooked until the end.
